You may have a picture content control where you want to replace the picture with a different picture. This post shows the Open XML SDK V2 code that is necessary to find a picture content control with an alias of \u201cMyPicture\u201d. It then finds the ImagePart, and then replaces the contents of the image part with a different image.<\/p>\n
